At some point in your career, your boss might hand you a piece of legacy code which was written by someone else a long time ago and your boss will tell you to learn this legacy code, fix it, and add new features to it.
But what exactly is a Legacy Code?
If you work in IT, that’s a term you’ll hear often in your career. Developers talk about it all the time. There’s no exact definition of what a legacy code is but to understand it better people define it as– Legacy code is a code maintained by someone who is not the main author.
And this is the definition you are going to hear the most when people talk about it.
One of the main reasons a project goes from normal code to legacy code is evolution of code bases and technology. For example, phones, which were originally very simple and there wasn’t a whole lot of code but as phones evolved, we got cell phones which needed more codes to run and then we got smartphones which needed a ton of code to run. As phone technology evolved, all the hardware and the software technology that went into them did as well and in that process of evolution a lot of code became legacy code because of the new codes that were written by developers. And so browsers, operating systems, language libraries are all constantly getting released, as new technologies and new hardwares develop.
And so every one or two years into a project, unless you are constantly upgrading versions and refactoring, things are going to be obsolete in your database. Similarly, if a senior developer leaves the company or a team moves on to another project the old software they are working on can become stale and discarded and can turn into a legacy code.
But today, times are fast changing and if you are looking for a career in IT without prior knowledge about coding you don’t have to worry because most elements of cloud computing do not require any code. Coding is not a prerequisite because most cloud services, such as Google Cloud, have their own APIs, which automates processes and organizes each asset with the software.
